Agar, a polysaccharide extracted from certain red algae, is widely used as a solidifying agent in microbiological media. Which of the following structural features contributes most to agar's gelling properties?
High degree of branching similar to glycogen.
Presence of β(1→4) glycosidic linkages exclusively.
The presence of sulfated galactose residues and the formation of double helices.
Its ability to form highly crystalline structures similar to cellulose.
Why doesn't cellulose react with iodine to produce a blue color?
It lacks the helical structure necessary for iodine complexation.
It contains fructose units instead of glucose.
It is a branched polymer and cannot interact with iodine.
It is insoluble in water, preventing the reaction with iodine.
